If you click on the link and read the rest of the article, it doesn't seem to be a done deal yet, the source is a post on a Facebook profile, and it is being funded by student money, so the CRs may have to have a liberal to make it a debate and not an evening of hate. There are also some comments on Pghlesbian.com too.
Here is more information from the Pittsburgh City Paper:

No April Fool's joke -- Coulter coming to Pitt
BY CHRIS POTTER
Fresh from her knee-slapping reference to presidential candidate John Edwards as a "faggot," Ann Coulter is coming to Pittsburgh on April 1. The conservative brick-thrower was invited by the University of Pittsburgh chapter of the College Republicans: She is scheduled to speak at 7 p.m. in Pitt's David Lawrence Hall.
"This isn't an April Fool's Joke!" proclaims an announcement for the event on Facebook, a social-networking site popular among college students. Indeed, publicity for the event has been scanty, but Pitt administrators and the Young America's Foundation -- a Virginia-based organization that books Coulter's campus appearances -- confirm Coulter is slated to appear.
BTW, I am former Pittsburgher, who is trying to get my local paper to dump the Coultergeist.
